Abstract: An analyte detection device includes a fluid impermeable layer having a first thickness and at least one inlet port having a diameter, the at least one inlet port defining a fluid pathway through the first thickness. The device also includes a reagent-hosting layer having a second thickness and including at least one of a chemical reagent and a bio-chemical reagent. The reagent-hosting layer is configured to radially receive a sampling fluid via the fluid pathway, where the sampling fluid is configured to interact with the at least one of a chemical reagent and a bio-chemical reagent in the reagent-hosting layer to indicate a characteristic associated with an analyte in the sampling fluid.

Abstract: Nanohole electrodes useful in opto-electronic devices, and in particular, organic photovoltaics devices incorporating nanohole electrodes, are disclosed. An exemplary embodiment includes a photovoltaic device with a first electrode comprising a nanohole film, a second electrode, and an active layer located between the electrodes. Methods of producing a nanostructured electrode are also provided.

Abstract: A protective coating for aluminate phosphors is described. The protective coating comprises at least a partial spinel coating having the general formula Mg1-xAl2(1-y)O4-3y-x, where 0≦x<1 and 0≦y<1. The coating is applied by an aqueous solution method which may be compatible with conventional fluorescent lamp manufacturing techniques.
